- Abstract
Cultivation of buckwheat arouses a growing interest due to dietetic values of groats and other food products obtained from its seeds. Mineral fertilization is one of the main factors modifying the quantity and quality of agricultural crops yield. The aim of the conducted study was to estimate the response of the common buckwheat cultivar Hruszowska to soil fertilization with magnesium and sulphur and foliar fertilization with microelements. The strict field experiment was conducted over 2012-2014. In this study, the pre-plant application amounted to the following rates per hectare: nitrogen - 20 kg in the form of ammonium nitrate 34%, phosphorus - 60 kg P2O5 - as 40% triple superphosphate and potassium in an amount of 60 kg K2O as 60% potash salt. The 1st order factor was fertilization with magnesium and sulphur (n = 4). Magnesium (20 kg·ha-1) was applied in the form of magnesium chloride, whereas sulphur (20 kg·ha-1) in the form of Vigor which contained 90% S. The 2nd order factor was foliar fertilization with microelements used in the form of the fertilizer Mikro Plus - a liquid mixture of micronutrients (B - 0.3%, Cu - 0.15%, Fe - 2.4%, Mn - 1.0%, Mo - 0.06%, Zn - 0.4%). The applied fertilization with magnesium, sulphur and microelements significantly modified the nutlet and protein yield of buckwheat, and resulted in a change in the chemical composition of the seeds. The highest yield of nutlets (1.6 t·ha-1) and protein (206 kg ha-1) was found after the combined application of magnesium and sulphur. In consequence of the use of combination of these elements, the highest contents of total nitrogen content in the seeds was also usually obtained. As a result of foliar application of microelements was found a significant increase in the yield of buckwheat nutlets amounted to 3.3%, and increase of protein yield by 2.3%, in compare with the control treatment. The obtained seed and protein yields and total nitrogen content in nutlets were strongly differentiated in individual years of the study.
